Mountable unit for biological signal measurement and biological signal measuring method

Abstract

Disclosed herein is a mountable unit for biological signal measurement, including: three electrodes; and a support body configured to support the three electrodes at positions corresponding to a positional relationship among a predetermined position on a forehead on one side of a face bounded by a midline, a temple position on the one side of the face, and a predetermined position on a zygomatic body on the one side of the face.

1. A mountable unit for biological signal measurement, comprising:
 three electrodes; and 
 a support body configured to support the three electrodes at positions corresponding to a positional relationship among a predetermined position on a forehead on one side of a face bounded by a midline, a temple position on the one side of the face, and a predetermined position on a zygomatic body on the one side of the face, wherein 
 the support body is provided with a fixture for fixing the support body by sandwiching head hair. 
 
     
     
       2. The mountable unit for biological signal measurement according to  claim 1 , wherein
 the predetermined position on the forehead is a position above the temple position, and the predetermined position on the zygomatic body is a position beside a tail of an eye. 
 
     
     
       3. The mountable unit for biological signal measurement according to  claim 1 , wherein
 the support body has a plate shape, and 
 at least part of each of the three electrodes is exposed in one surface of the support body having the plate shape, and suction cups or adhesive materials surrounding the exposed electrode parts as concave parts are provided. 
 
     
     
       4. The mountable unit for biological signal measurement according to  claim 1 , wherein
 the support body is provided with a circuit that measures potential difference between the electrode supported at the position corresponding to the predetermined position on the forehead and the electrode supported at the position corresponding to the temple position, and potential difference between the electrode supported at the position corresponding to the predetermined position on the zygomatic body and the electrode supported at the position corresponding to the temple position.
